Installed Viper 5701 on 2004 Explorer: Eddie Bauer. Everything works but now when I press the brakes, they are hard to push. I've had it to a Ford dealer and they are stumped. Everthing works on the remote starter relating to the brakes (car shuts off after brakes are applied when starter via remote). Short of disconnecting what I've done, I'm looking for more ideas.

disconnect the brake wire that you connected to the car and see if that corrects the issue

i have never had an issue like this in my 6 years of installing

someone else may chime in with some more info

Did you knock off the vaccum line to the brake booster when running the tach?

That's a negative. Is this common knowledge to do so? I didn't see anything relating to that info when researching installation instructoions. What would the removal of the hose do during the installation of the tach?

Nevermind that last post. Just started thinking of it more. Your thinking that there may be air in the brake lines?

He means there is a large hose going to the brake booster under the hood that comes from the motor. This is vacuum and makes the brakes work easier. Check it...

Alright, still need to look at that vaccum hose but I really feel that I didn't touch that. I've looking for an accurate wiring diagram of the 2004 Ford Explorer. I want to compare something to the diagram I found originally. Can anyone post a link?

With the engine not running, press the brake pedal, notice the feel. Now start the engine and press again. If it feels the same as it did with the engine not running, I too vote for the detached vacuum hose. Power brakes = Vacuum assisted brakes. No vacuum assist, no power brakes.

Found another diagram that matches what I used. Thanks Idiot...

I've had the car off, pumped the brakes and noticed how hard it gets to push. I turn the car on and the brake pedal release and is easier to push (brake booster engaging I'm assuming). The problem lies in when I put the car in to drive, you notice the same hard feel as if the car is off and you've just pumped the brakes. I'm going to go back underneath and make sure that is nothing that is back feeding in to the control unit or the brakes... I still need to attempt to disconnect the brake wire to check if that resolves anything. Will post when I find something out.

The brake wire controls the brake lights - I've never seen a car that had any sort of feedback when you push the brakes that made something work.

If the problem is electrical - I would check to make sure your ignitions and accessory circuits are powered correctly.

It sounds like the problem occurs either when you remote start or start with key? If that is the case, then more then likely there is something wrong with the brake system of the car. Possibly a detached vacuum line. :)
